A new JAMA Internal Medicine study claims that those who get wisdom teeth pulled, and are prescribed opioids, are more likely to have problems with the drug down the road. The numbers may look convincing, but the study is a retrospective analysis –– which is the least reliable type because manipulated variables can change the outcome. Was this the case here? Biostatistician and ACSH advisor Dr. Stan Young (left) weighs in. He is not shy.

How much sleep is enough? Can there be both too little and too much? A new study thinks they have identified that Goldilocks range which is just right.

A recent and thorough investigation of the scientific literature found no evidence that chiropractic care can prevent or stop the disease in its early stages. The researchers urged chiropractors to “cease such activities until, if ever, new evidence emerges.” It’s doubtful that chiropractors will follow this advice.

In what can only be described as a purposeful attempt to damage its own poor reputation even further, PETA's latest campaign is to change our "speciesist" language.

Chinese President Xi and President Trump are trying to hammer out an agreement to stop fentanyl from flooding into the United States. Whatever they come up with may help, but only so much. In this case, organic chemists have more power than presidents. Here's why.

Plants can be turned into fuels and chemicals, but much of their stored value is lost in the woody component that's hard to break down. A sea creature, among others, has found a way to get at that additional value. It provides both something we can use – and a reminder about the power of nature and evolution.

If you're a Chinese citizen, don't irritate the Chinese government. Otherwise, you'll be subject to "re-education" and then possibly deployed as a pawn of the regime. Apparently, the Chinese scientist who gene edited a baby is now learning this lesson the hard way.

The interaction of supply and demand is an initial economic lesson. The FDA approves new drug's safety and efficacy. But it's the payers – Medicare and the insurance companies – that determine the true supply. Before we begin to discuss cost, let's first learn about supply.

The Holiday Season is in full swing, and we here at the American Council on Science and Health continue our fight on behalf of good science! Here's where we appeared in recent days.

"No sooner had the warm liquid mixed with the crumbs touched my palate than a shudder ran through me and I stopped, intent upon the extraordinary thing that was happening to me." That's ACSH friend Dr. Michael Shaw channeling Proust on the power of smell. Of course, it cuts both ways. Body odor? Why do we have it? Do deodorants work? How about hygiene? Is "old-person smell" real? Just take a sniff of what's in this fascinating piece.
